HEADLIGHT CONSTRUCTION.

Application filed December 5, v1921.

To all whom it may concern:

Be it known that I. rimmer Myrrnonr, a

citizen of the United States, and a resident of Connersville, county ofFayette, and State of Indiana, have invented a certain new and usefulHeadlight Construction; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, in which like numerals refer to like parts.

This invention relates to a lamp construc tion, and more particularly tothe means for clamping the lamp door and reflector to the casing,whereby they will be maintained in position under spring tension and bereadily removable therefrom.

The particular feature of the invention lies in a single springconstruction for yield: ingly securing the lamp door and reflector inposition, and causing the lens to be clamped against the reflector orcasing under spring tension in such a manner, that by a rotary movement,the spring will become disengaged and the lamp door and reflector may beremoved.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a front elevation of a lamp with a portionthereof cut away to show one of the clamping springs mountedon theinside thereof. Fig. 2 is a section of the lamp showing a rear elevationwith the back portion of the lamp removed for disclosing the clampingmeans. Fig. 3 is a section taken on the line 33 of Fig. 2. Fig. 4 is aside elevation of a portion of the lamp with the door rim removed.

In the drawings there is shown a lamp construction having a casing 10,reflector 11, door or lens rim 12 and lens 13. The casing has aninwardly and radially ex tending flange 14 about its outer edge, and thereflector 11 is provided with a radially and outwardly extending flange15, said flanges being arranged so as to be clamped together ashereinafter set forth. Between the flange 15 and the reflecting surfaceof said reflector, there is an outwardly projecting portion having agroove extending about the surface thereof to provide a seat for thecord 17 against which the lens 13 is pressed for sealing the reflectorand pre- Serial No. 519,952.

venting dust and moisture from entering therein.

Secured on the inner surface of the flange 14, there is a springclamping member 18 comprising a strip of spring metal having an end 16reduced at 19 adapted to pass through a suitable opening in the flange14 and extend therethrough to yieldingly engage and clamp the flange 15of the reflector by the extended lip or end 16. The other end of saidspring is secured by extending it through a suitable slot in said flangewhich forms a permanent seat therefor. The ends of said spring are,therefore, secured to said flange in such a manner as to cause theintermediate portion thereof to bow outwardly from said flange, as shownin Fig. 8. Said spring is formed with a saddle 21 comprising acomparatively small recessed portion included between adjacent shouldersfor forming a locking seat.

Rigidly secured upon the door or lens'rim 12, there is a'projectingmember 22 having one end 23 thereof bent so as to loosely hold the lens13 in position while the door is being mounted or dismounted, and theother end 24 being arranged to extend radially and inwardly from saidrim so as to engage the spring 18 and slip into the saddle 21 forremovably locking said door rim in 'posi tion on said casing. Inmounting the door rim and reflector upon the casing, the reflector isplaced in position so that thefianges 14 and 1-3 lie adjacent eachother, the reflector is then turned so as to cause the pro- ]ecting lip16 to extend through an opening therein and yieldingly engage saidflange, thereby clamping it in fixed position under spring tension. Thelens 13.is placed in said rim so as to be maintained therein by the ends23 of the member 22. The rim is then mounted about the outer edge of thecasing and rotated thereabout until the in wardly extending end 2d ofthe member 22 passes through a slot 25 in the periphery of the casing,engaging the upper surface of the spring 18, away from the door rim, andsliding thereover, causing it to be pressed downwardly against thespring tension thereof until said end falls into the saddle 21 betweenthe adjacent shoulders. Further movement of said member 22 is thenarrested by the end of the slot 26 being reached and its abutmentagainst one of said 0g :1 spring ternictliute portion of Within saidcasesure extending in 1d closi relativel v tn sting of 21 ie flange ofspring ex- (l extenilin e0 am the Width of the i'crsely to the {DES ofthe earsrounding the (1 within the g; flange adjacent i-r en Slid springmemng said rlcsure to i infurneil sub- 65 e sur ineuni: an outturnmlannular e inturned flange 0% the ng, and means 70 g, retle-tur 2n ctioncoi'nprising; an inning 11 fl i positi ans cons extenii her said cusiiugg its oil he in g houexl inwardly from snul said ill engage an eel;
